perfSONAR User Q&A and Other Discussion

[Philip Papadopoulos <>]

The current packaging of perfSONAR introduces a package conflict

specifically,

Those two rpms conflict with each other. 

http://linux.mirrors.es.net/perfsonar/rpms/el6/x86_64/main//RPMS/python27-mod_wsgi-3.2-3.el6.x86_64.rpm

http://mirror.pac-12.org/6.6/os/x86_64/Packages/mod_wsgi-3.2-7.el6.x86_64.rpm

The first one is supplied by perfSONAR the latter is the system package for use with the system-supplied python (2.6.6 on CentOS 6.6)

Both packages lay claim to 

/etc/httpd/conf.d/wsgi.conf

/usr/lib64/httpd/modules/mod_wsgi.so

This conflict makes it impossible to install other software that uses mod_wsgi and system Python. Notably, the globus-connect-server has this issue.

The different versions of the mod_wsgi.so are not compatible with each other. PerfSONAR should really put this library in a different location and then have all PS packages that need to use it (e.g. esmond, preload that library path).
